N Audio Panel Description AUDIO PANEL DESCRIPTION The KMA 29 audio control panel provides audio system control for the cockpit crew and passengers. The panel also provides an interface to the passenger address (PA) system and aural warning system. The audio panel also includes a marker beacon receiver. The audio panel is used to make audio selections for all audio communications to and from the cockpit crew. The audio panel receives inputs from all audio communication channels and aural warnings.
Audio Panel Description N There are four unswitched inputs (aircraft hard-wired and configured) available for traffic or terrain awareness warning system (TAWS), autopilot disconnect, and/or radar altimeter warning. The audio panel always supplies the audio from one or two of the audio inputs to the pilot’s and copilot’s headset and cockpit speakers outputs during normal operation.
N Audio Panel Controls AUDIO PANEL CONTROLS The front panel drawing of the audio panel is shown below.
Audio Panel Controls N SPKR/PA (SPEAKER/PASSENGER ADDRESS) SWITCH The SPKR/PA switch has three functions: • Speaker ON • Speaker OFF • Passenger address system ON. The SPKR/PA rocker switch can be pushed to the left or right. Each time the right side of the switch is pushed, the mode changes from left to right as indicated by the light emitting diodes (LEDs) and does not wrap around.
N Audio Panel Controls The COM 1 through COM 5 MIC buttons are used to select the associated radio transmitter. The receiver audio for the selected transmitter is automatically selected. A lighted arrow located above each button indicates that the button has been pressed and that the mode is active for the left (pilot) side, right (copilot) side, or both sides. This depends upon the mode of the audio panel operation split or duplex mode.
Audio Panel Controls N CREW/PAX ICS VOL KNOB AND PUSH EMG/OFF SWITCH CREW/PAX ICS VOL (CREW/PASSENGER INTERCOM SYSTEM VOLUME) KNOB The CREW/PAX ICS VOL knob control adjusts the loudness of the intercom only. Turning the inner knob clockwise and counterclockwise sets the volume of the headphone up or down respectively for the CREW intercom. Turning the outer knob controls the speaker or headphone volume for the passengers (PAX) intercom.
N Audio Panel Controls COM AUDIO SELECTOR BUTTONS The COM 1 through COM 5 AUDIO buttons are used to select the associated receiver audio. The selected transmitter receive audio is automatically selected. Pressing a button turns on the associated radio audio. The pilot can identify which receivers are selected by noting which of the green lights are illuminated.
Audio Panel Controls N When the LED above the MKR button is OFF, the marker audio is muted. The visual indications on the PFD will still operate when the aircraft passes over the marker. MKR SENS (MARKER BEACON SENSITIVITY) BUTTON The MKR SENS button controls the marker beacon receiver sensitivity. The button alternates between the HI and LO settings.
N Audio Panel Operation AUDIO PANEL OPERATION The audio panel receives audio from remote radio units, decodes the audio, controls the gain (volume) and routing of the various channels, filters audio signals, and output the audio to various speakers and headphones. It controls microphone inputs to various radios, intercom and passenger address systems. Amplifiers are included for driving headphones and speakers.
Audio Panel Operation N COMMUNICATION AND NAVIGATION AUDIO OPERATION Pressing any of the communication (COM) or navigation (NAV, ADF, DME, AUX, or MKR) audio selector buttons enables the associated audio and the LED above the button is lit. Pressing the same audio selector button again turns the audio for that channel and the LED above the button off. The pilot and copilot can select and listen to more than one communication or navigation audio at a given time.
N Audio Panel Operation munication capability regardless of the condition of the unit. Any time power is removed or turned off, the audio selector is placed in the EMG mode. In the EMG mode, one or two of the unswitched audio inputs are supplied to the pilot headset. Also, in the EMG mode, audio signals are present in only one ear of a stereo headset. MARKER BEACON OPERATION The marker beacon receiver uses visual and audio indicators to alert the crew when the aircraft passes over a 75 MHz transmitter.
Audio Panel Operation N Pressing and holding the MKR MUTE/TEST button for five seconds causes the marker beacon discretes to go high for one second in order to test the marker beacon. The marker beacon annunciations are shown on an external display. SPLIT MODE OPERATION NOTE: The Split Mode is used only in a single audio panel environment. It allows the pilot and copilot to transmit and receive on different COM radios. The typical Split Mode operation is as follows: 1.
N Audio Panel Operation INTERCOM OPERATION The intercom system is an IntelliVox® automatic voice activated system. The IntelliVox® circuitry eliminates the need for manual adjustments of the squelch. Through three individual signal processors, the ambient noise appearing in all six microphones is constantly being sampled. Non-voice signals are blocked. When someone speaks, the microphone circuit opens, placing their voice on the intercom.

N Audio Panel Operation While in the intercom ISO mode, Entertainment 1 is muted for the pilot. The copilot hears Entertainment 1 at a normal level. The music automatically mutes when either the copilot or passengers speak and then gradually returns to the original listening level when the intercom or radio conversation ceases. The pilot does not mute the music while in the ISO mode if the PTT switch is pressed to transmit or if the pilot speaks while on the phone.
Audio Panel Operation N TELEPHONE MODE OPERATION When enabled in the installation, COM 5 serves as a full duplex interface for telephone systems. When interfaced with specific aircraft approved FAA/FCC cellular telephone equipment, the audio panel can serve as an audio control and distribution center. The audio panel acts as an audio interface between aircraft headphone and microphones and telephone. The pilot selects telephone by selecting COM 5 on the audio panel.
